First-run notes

The app isn't code-signed yet (signing is on our roadmap), so your system will show a warning the first time. This is expected. Here's what to do:

macOS will say the app "cannot be verified". Open System Settings → Privacy & Security and choose "Open Anyway".

Windows may show "Windows protected your PC". Click "More info", then "Run anyway".

Make the AppImage executable first: chmod +x, then run it. The .deb installs normally.
